The client host module dont promp when trying to connect

Hi, I installed TV host module  on 2 computers need me and I try to connect to it using my account. On the "client" computers, the password is set to 6 caracters. When I try to connect, on my computer the password popup appear, but the host module on the client computer dont show. So my "client" can tell me the password.  It's a TV problem or a window?

Thank you
